Liquid ejecting apparatus, liquid ejecting method, and medium

A liquid ejecting method using a liquid ejecting apparatus,

• the liquid ejecting apparatus including:
• a first ejection head having a plurality of first nozzles;
• a second ejection head having a plurality of second nozzles;
• a conveyor, a recording medium being conveyed by the conveyor in a conveyance direction with respect to the first ejection head and the second ejection head;
• a carriage, the first ejection head and the second ejection head being moved by the carriage in a movement direction crossing the conveyance direction;
• and
• a controller,
• wherein the first ejection head and the second ejection head are disposed so that a part of the plurality of first nozzles and a part of the plurality of second nozzles overlap with each other in the conveyance direction in a joint area,
• the liquid ejecting method comprising:
• obtaining information on drying risk of a liquid in the part of the plurality of first nozzles and the part of the plurality of second nozzles;
• selecting one mask of a plurality of masks depending on the drying risk;
• and
• performing printing based on a print job by using the selected one mask, wherein:
• each of the plurality of masks defines a first ratio and a second ratio;
• the first ratio is a ratio of increasing toward a first side in the conveyance direction of a first use-permission rate, the first use-permission rate being a rate of a number of a nozzle to be used in ejecting of the liquid in a row to a number of the first nozzles arranged in the moving direction in the row, the first nozzles being included in the part of the plurality of first nozzles;
• the second ratio is a ratio of decreasing toward the first side in the conveyance direction of a second use-permission rate, the second use-permission rate being a rate of a number of a nozzle to be used in ejecting of the liquid in a row to a number of the second nozzles arranged in the moving direction in the row, the second nozzles being included in the part of the plurality of second nozzles;
• and
• the first ratio is different from each other among the plurality of masks, and the second ratio is different from each other among the plurality of masks.

A non-transitory and computer-readable medium storing a program executable by a controller in a liquid ejecting apparatus,

• the liquid ejecting apparatus including:
• a first ejection head having a plurality of first nozzles;
• a second ejection head having a plurality of second nozzles;
• a conveyor, a recording medium being conveyed by the conveyor in a conveyance direction with respect to the first ejection head and the second ejection head;
• a carriage, the first ejection head and the second ejection head being moved by the carriage in a movement direction crossing the conveyance direction;
• and
• the controller,
• wherein the first ejection head and the second ejection head are disposed so that a part of the plurality of first nozzles and a part of the plurality of second nozzles overlap with each other in the conveyance direction in a joint area,
• the program is configured to cause the controller to:
• obtain information on drying risk of a liquid in the part of the plurality of first nozzles and the part of the plurality of second nozzles;
• select one mask of a plurality of masks depending on the drying risk;
• and
• perform printing based on a print job by using the selected one mask, wherein:
• each of the plurality of masks defines a first ratio and a second ratio;
• the first ratio is a ratio of increasing toward a first side in the conveyance direction of a first use-permission rate, the first use-permission rate being a rate of a number of a nozzle to be used in ejecting of the liquid in a row to a number of the first nozzles arranged in the moving direction in the row, the first nozzles being included in the part of the plurality of first nozzles;
• the second ratio is a ratio of decreasing toward the first side in the conveyance direction of a second use-permission rate, the second use-permission rate being a rate of a number of nozzle to be used in ejecting of the liquid in a row to a number of the second nozzles arranged in the moving direction in the row, the second nozzles being included in the part of the plurality of second nozzles;
• and
• the first ratio is different from each other among the plurality of masks, and the second ratio is different from each other among the plurality of masks.
